When the composite image output process is started, the CPU 50 reads the image information of the support image assigned to the predetermined area of the RAM 54 (step 130), and the support image information and the image information input from the CCD camera 26A are read. The images are combined according to a predetermined rule (step 140), and the combined image is output to the built-in monitor 40 (step 150). At this time, only the image information input from the CCD camera 26A is output from the external image output terminal 66, as in step 120. That is, by this composite image output processing, not only the image information input from the CCD camera 26A but also the support image previously stored in the predetermined area of the RAM 54 is composited and reproduced on the built-in monitor 40.

Next, the process of generating the support image used in the above synthetic image output process will be described. FIG. 4 is a flow chart of a time setting program which is terminated or interrupted by the material presenting program shown in FIG. 3 when a predetermined key input is made. When this time setting program is processed, the CPU 50 uses the built-in monitor 40 to display time information for using the material presentation device 20,

As shown in the figure, most of the image on the built-in monitor 40 is used as an area for displaying the image information from the CCD camera. At the right end, the current time (PM 3:15 in the figure) is displayed and the start time is displayed. The elapsed time is visually displayed on a bar graph whose starting point is time (PM 2:00 in the figure) and ending point is the end time (PM 4:00 in the figure).

Further, the material presenting apparatus 20 of the present embodiment can store the character assisting image in a predetermined area of the RAM 54 which is scheduled to be read in step 130 of the material presenting program.

FIG. 7 is a flowchart showing a character support program for writing a character support image in the predetermined area. Similar to the time support program, this program is executed when the combination mode is instructed and the condition that significant character string information is stored in a predetermined area of the RAM 54 is satisfied.

In this program, first, n pages (n is a natural number starting from 1) are selected from the character string information over a plurality of pages.

A character support image is generated from this character string information (step 4
10) The generated character support image is stored in a predetermined area of the RAM 54 which is scheduled to be read in step 130 of the material presentation program (step 420).
Then, it is determined whether or not there is a page break input (step 430),
Only when a page feed is input, the variable n is incremented by 1 (step 440) and the process returns to step 400. That is, by executing the material presenting program of FIG. 3 after the processing of this program, the image displayed on the built-in monitor 40 changes into a composite image of the image from the CCD camera 26A and the character assisting image. .

FIG. 8 is an explanatory view of the display on the built-in monitor 40 when the character assisting image is combined. In this case,
The character string information stored in a predetermined area of the RAM 54 is displayed on the right end of the screen, and both the image of the CCD camera 26A and this character string information can be viewed at the same time.

In order to write this character string information in a predetermined area of the RAM 54, an editor or word processor program is processed by the CPU 50 and the keyboard 3 is used.
It does not matter which method is used, such as directly key-typing from 2 or transferring character string information created by another device to a predetermined area of the RAM 54.

Further, step 13 of the material presentation program
When both the time assistance image and the character assistance image are stored in the predetermined area of the RAM 54 which is scheduled to be read out at 0, the image synthesizing process in step 140 includes three images including the image from the CCD camera 26A. Execute the synthesis process of. FIG. 9 shows a display example of the built-in monitor 40 by the synthesizing process of the three images. In this case, the CCD camera image area shown in FIG. 8 is slightly narrowed and displayed, and
The time support image is arranged in a small area below the screen, and the character support image is further arranged similarly to the display area in FIG.

You can get information about time. Moreover, as shown in FIGS. 6 and 9, the time support image of the present embodiment displays the usage time and elapsed time of the material presenting apparatus 20 in a graph form. Therefore, even if the display screen of the built-in monitor 40 is small, the elapsed time can be grasped instantly, and the time distribution for ending the explanation to the viewer within the scheduled time can be intuitively understood. it can.

Further, when the image information to be the support is a character support image, it is necessary to dictate the image shown to the viewer without forgetting the matters to be explained, without preparing a memo or the like. You can Moreover, since the character support image is displayed on the built-in monitor 40 of the material presentation device 20, it is not necessary to deviate from the line of sight of the viewer as in the case of checking a memo on the desk.

Further, the material presenting apparatus 20 having the above-described structure can display the image only on the built-in monitor 40 in advance without displaying the image on the television directed to the viewer by appropriately operating the operation unit 30. By checking, the display of the wrong video is not displayed on the television side, and the video can be easily corrected.

The embodiment of the present invention has been described above.

For example, in the above-described embodiment, the built-in monitor 40 is a retractable type, and it is easy to reduce the size of the screen.
Even if it is embedded in 0, it does not matter. Further, in the embodiment, the example in which the time support image is displayed in the bar graph format for easy intuitive understanding is shown, but the elapsed time and the remaining time may be displayed in numbers.

Further, in the above embodiment, the image processing circuit 60 is used.
The division method is used to create the composite image in order to reduce the information processing load of the, but the images can be overlapped and the display area of each image can be changed, enlarged, or reduced using a pointing device such as a mouse. An image processing technique such as the above may be appropriately adopted.

Further, among the plurality of support images, the operation unit 3
It may be selectively displayed on the television of the viewer side by the operation of 0. For example, unnecessary information directed to the viewer can be selectively removed by displaying only the built-in monitor 40 without displaying the time support image, which is unnecessary for the viewer, on the television on the viewer side.
